Genesis 9:13

I set my bow in the clouds The rainbow, it is likely, was seen in the clouds before, but was never a seal of the covenant till now. Now, observe, 1st, This seal is affixed with repeated assurances of the truth of that promise, which it was designed to be the ratification of; I do set my bow in the cloud, Genesis 9:13. It shall be seen in the cloud, Genesis 9:14, and it shall be a token of the covenant, Genesis 9:12. And I will remember my covenant, that the waters shall no more become a flood, Genesis 9:15. Nay, as if the Eternal Mind needed a memorandum, I will look upon it that I may remember the everlasting covenant, Genesis 9:16. 2d, The rainbow appears when the clouds are most disposed to wet; when we have most reason to fear the rain prevailing, God shows this seal of the promise that it shall not prevail. 3d, The rainbow appears when one part of the sky is clear, which intimates mercy remembered in the midst of wrath, and the clouds are hemmed, as it were, with the rainbow, that they may not overspread the heavens; for the bow is coloured rain, or the edges of a cloud gilded. As God looks upon the bow that he may remember the covenant, so should we, that we also may be ever mindful of the covenant with faith and thankfulness.
